If you’ve been reading Bark’s blog for any length of time, you know my pet peeve is dog waste. I hate wrapping it in plastic and adding it to the landfill almost as much as I resent people leaving it on the street and in the park. So I LOVE lemons-to-lemonade/sow’s-ear-to-silk-purse stories that start with this all too bountiful raw material.
Therefore, howls of gratitude to Cambridge, Mass., artist Matthew Mazzotta who has created a dog-poop-to-methane converter that fuels a park light, known as the “Park Spark.” Mazzotta has succeeded where others, including the City of San Francisco, have failed.
